MTV’s guiltiest pleasure premiered to an audience of 8.8 mil viewers on Thursday.

Fallon dedicated his own Aug. 4 show to the infamous guidos and guidettes, who jetted off to Florence, Italy for the fourth season of their MTV reality show. Between fist pumping, graphic tee’s and wigs styled in Nicole "Snooki" Polizzi and Paul "DJ Pauly D" Delvecchio’s signature coifs, Fallon included a product promotion for the newest addition to the Jersey Shore franchise.

“A lot of bottled water comes from lakes or streams. That’s disgusting,” he says in the spot. “That’s why Jersey Shore water is bottled straight from the only source I trust. The Jersey Shore hot tub.”
